Model tests on wrap-faced geosynthetic reinforced soil wall with gravel soil backfills and its observed deformation patterns
碩士 === 國立雲林科技大學 === 營建工程系碩士班 === 100 === 本研究進行一系列平面應變模型試驗以探討回包式加勁擋土牆之垂直承載力與變形特性。本研究之模型牆體尺寸為183cm(長)×80cm(寬)×112cm(高),所採用之背填材料為礫石(D50=5.23mm),加勁材則採用三種勁度相異之PET地工格網。以寬度30cm條形基礎置於擋土牆頂面並於其上施加垂直載重。本研究藉由影像分析方法以觀察土體內部於試驗加載過程中之變形與剪裂帶樣式發展情形,並記錄加勁格網於試驗加載後之拉出與斷裂破壞情形。 本研究試驗結果顯示加勁土之基礎極限承載力較未加勁者顯著增加,加勁土達極限承載力所需之垂直...
